This rifle must surely be the same one I saw sold at an auction in Chatham, Kent, a few months ago.
There was a Whiscombe JW50 in the same sale. They were from the estate of deceased local man.
The one I saw also had an Optima gamekeeper scope, and a couple of small blemishes on the action, the serial no. may have been 24, but I'm not entirely sure.
There was a thread on here about it at the time, but I can't find it
It sold for around £1000, so if it is the same one, it will be interesting to see how much it goes for, maybe I should have bought it.
